Samsung TU-3500 (c. 1981)
Not much is documented about the Samsung TU-3500. The Archive doesn't have a manual or original sales literature for it yet. The only surviving record is a specification listing in High Fidelity (1981, p.138). It gives the tuner's size as 2 15/16 by 16 15/16 by 9 3/4 inches and its weight as 6 lb. 6 oz. net.
Known specs from that listing:
- Sensitivity for 50 dB quieting: 15.5 dBf / 37 dBf
- Signal-to-noise: 72 / 70 dB
- THD: 0.08% / 0.15% at 1 kHz
- Selectivity: 70 dB
- Capture ratio: 1 dB
- Separation: 40 dB, 50 Hz to 10 kHz
- Subcarrier rejection: 65 dB
No production dates, original price or circuit details have been documented so far. For now, that spec listing is all there is.
